STIMULATION SYSTEM FOR CONTROL OF THE PARALYZED HAND IN THE C5/C6 INJURY

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。这项研究旨在评估植入式刺激系统的性能，该系统旨在为高位脊髓损伤(四肢瘫痪)患者提供瘫痪的上肢的激活和控制。这项工作的意义在于，功能性神经肌肉刺激可以为四肢瘫痪受试者提供替代方法无法获得的操纵能力。功能性电刺激(FES)硬件已经被开发出来，以提供掌侧抓握/释放。研究计划是将这种硬件部署到适当选择的四肢瘫痪受试者身上，并评估这些设备是否为他们提供了传统矫形术所能使用的功能之外的功能。还在评估旨在扩展基本FES手系统功能的增强措施，包括将手的固有肌肉纳入手握手，以及使用植入式关节角度传感器(IJAT)来提供命令/控制。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. This study is to evaluate the performance of an implantable stimulator system designed to provide activation and control of the paralyzed upper extremity in high level spinal cord injury (tetraplegic) patients. The significance of this work is that functional neuromuscular stimulation may provide tetraplegic subjects with manipulative capabilities unavailable by alternative means. Functional Electrical Stimulation (FES) hardware has been developed to provide palmar and lateral prehension/release. The research plan is to deploy this hardware to appropriately selected tetraplegic subjects, and to assess whether the devices provide them with function beyond that which can be employed by conventional orthotics. Enhancements designed to expand the basic FES hand system's function also are being assessed, including incorporating the intrinsic hand muscles into the hand grasp and the use of an implantable joint angle transducer (IJAT) to provide command/control.
